Workaround(s)
BinaryReader and BinaryWriter are used to read and write to and from a number of different stream types, not just local files. Some of these streams may be communicating with devices that require Big-endian format data and it would be extremely useful if BinaryReader and BinaryWriter supported this.

Version Currently Used

Visual Studio 2010 Beta 1
Operating System Currently Used
Windows 7
Suggestion
Give System.IO.BinaryReader and System.IO.BinaryWriter a constructor parameter to flip them into Big-endian mode.

Really guys I wish you would spend more time improving and fixing the existing framework rather than adding ever more modules. The fact that the BinaryReader can't handle big endian is so fundamentally rubbish that it should have been sorted in version 1.1 not version 6.

Thanks again for taking the time to report this. Unfortunately, we won't be able to get to this for the next release of .NET, so I'm resolving this as Won't Fix.

VHD file format footer also lays out their integer fields as big endian

Hi Hasl;jfaksljfhlkasjfhlaskjdfhl,

Thanks for the suggestion! Adding the ability to specify the endianness of BinaryWriter/Reader would be useful. Unfortunately we aren't planning to add support for this in .NET 4, but this is something we'll consider for a future release. Therefore, I'm going to go ahead and keep this suggestion open for tracking.

Please let me know if you have any questions or concerns at justinv at microsoft dot com.

You can also use Array.Reverse:


     Array.Reverse(aData, 12, 4);
     ClientAddr = BitConverter.ToUInt32(aData, 12);

Use a third-party class library such as described at http://stackoverflow.com/questions/1540251/binarywriter-endian-issue
